Diff for "MC_model"

Differences between revisions 2 and 3

Purpose:

To prepare a noise model of the MC and prepare an error budget for MC length fluctuations

Step 1. Collection of existing tools and models prepared by others.

Step 2. Prepare a toy model of a feedback loop with two noise sources

Step 3. Make a model for the MC -> PSL feedback loop with various sources of noise

Step 4. Measure the MC loop noise

Step 5. Obtain the error budget plot.

Step 6. Include ASC noise from the WFS loops in the model

Step 7 Measure ASC noise in the instrument

Step 8 Improve the ASC servo filter shape to reduce the ASC noise injected into the MC loop.
